What it does

mttr is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

From the publisher's description, Electra Index matched it to one capability: web research. That makes it a candidate for tasks such as fact-check a document or find influencers.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

  • mttr_links · The links of a site from its latest run: broken ones by default, or all, those in page content, or the other sites linked to. Link text read from the site comes under "quoted".
  • mttr_topics · What a site covers: its subjects and the pages under each, pages competing for the same search, and places a subject is missing from. A model named the subjects, so names come under "quoted".
  • mttr_structure · How a site is put together: its sections, how many clicks each sits from the home page, how much of each is linked from page content, and the links between sections.

  • mttr_rules · The rulebook: every rule mttr checks, with its stage, its weight and how to fix a failure.
  • mttr_similar · Pages of a site that mean nearly the same thing, grouped, which may compete for one search. With a path, the pages nearest that page, each with the two passages that come closest. Read from vectors of the page text, so the site must have be
  • mttr_near · The sites closest in meaning to one site, closest first: the ones writing about the same work, which are its likeliest rivals. Read from one vector a site kept in the catalog, so both sites must have been embedded.
  • mttr_leaderboard · The public leaderboard: every ranked site by the score of its latest read, places shared on a tie, or the board of one crowd: a line of work with "in", a state, a city in that state, a size, or any of them together, each place counted as a
  • mttr_explore · One thing mttr knows and every way on from it, each edge marked by what made it: meaning (close in meaning, never better or cited), links (pages linking between sites, or between pages of one site, with their anchor text) or rules (code che
  • mttr_markets · The markets last found: groups of sites close in meaning, each named by the site at its centre, largest first. A site in a market is writing about the same work as the others in it.
  • mttr_search · Ask a question, such as a buyer would, and get the passages that answer it best, and each site once by its best passage under "bySite", from the sites closest to the question, one market, or named sites. At most 12 sites are read. Passages
  • mttr_examples · How other sites pass a page rule a page fails: pages on sites in the same market, or the nearest sites, that pass the rule and are closest to the page in meaning, each with the passage that comes closest. Worked examples for writing the fix

  • mttr_gaps · Content gaps: subjects a site’s rivals write about that nothing on the site comes close to in meaning, the one most rivals cover first, each with the rival pages and the nearest page here. Page titles come under "quoted".
  • mttr_tells · The signs of generated text on a site's pages: hidden characters that can carry a watermark or hidden instructions (with any message spelled out in tag characters), chat and markdown left in, placeholders never filled in, stock phrasing, an
  • mttr_competitors · A site's competitors: where it is (from the address or phone numbers on its own pages), the sites near it that do similar work by meaning, everyone near it, and sites doing similar work elsewhere, each with score, pages, and how many sites
  • mttr_backlinks · The sites mttr has read that link to a site, the most pages first, with how many sites were counted. Links from sites mttr has not read are not known.

  • mttr_visits · Who fetched a site's pages in the last 28 days against the 28 before, counted by the site's own server: people, people an assistant such as ChatGPT or Perplexity sent, and crawlers by name, AI crawlers marked. By day, by crawler, by assista
  • mttr_queries · The searches Google showed a site's pages for, from Search Console, with clicks, impressions and average place: by query, by page, or only those close to the top (places 4 to 20). Only sites whose owner added mttr in Search Console have any

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
